Advanced Grade: UC5115 (The Cast Iron Expert)

The UC5115 grade is Mitsubishi's premium CVD solution specifically for cast iron. It features a specialized coating layer that offers incredible abrasion resistance, which is essential when dealing with the "sand" and abrasive nature of gray and ductile iron. This ensures a significantly extended tool life even at the high cutting speeds required by modern CNC machining.

GH Chipbreaker Geometry

The GH (General Heavy) chipbreaker is designed with a strong cutting edge to withstand high loads. In precision machining, stability is key; the GH geometry prevents edge chipping during heavy roughing passes and handles varying depths of cut with ease, ensuring superior chip control in cast iron materials.

Recommended Cutting Parameters

Optimized for Cast Iron (K-Class):

  • Cutting Speed (Vc): 150 - 350 m/min (490 - 1150 SFM)
  • Feed Rate (f): 0.20 - 0.50 mm/rev (0.008 - 0.020 ipr)
  • Depth of Cut (ap): 1.0 - 4.5 mm

*Pro Tip: For gray cast iron, higher cutting speeds can be used to improve surface finish.*

Global Verified Customer Feedback

⭐⭐⭐⭐⭐ "Cast Iron Beast" - Mark T., USA
"Switched to UC5115 for our ductile iron housings. The GH breaker handles the scale perfectly. Tool life is twice our previous brand."

⭐⭐⭐⭐⭐ "Reliable Roughing" - Lars H., Germany
"Very stable insert for high-feed roughing. The 6 edges make the cost-per-part unbeatable for mass production."

⭐⭐⭐⭐ "High Speed Quality" - Kenji S., Japan
"Consistency is why we buy original Mitsubishi. UC5115 keeps its edge even when we push the RPM. Excellent for gray iron."

⭐⭐⭐⭐⭐ "Great Service" - Liam F., Australia
"Arrived quickly in original packaging. These GH breakers are tough and don't chip on interrupted cuts."

⭐⭐⭐⭐⭐ "Unbeatable Cost" - Pavel D., Poland
"6 edges on a trigon insert is a huge advantage. UC5115 is our go-to for all cast iron CNC turning jobs."

Technical Q&A

Q: Is UC5115 suitable for steel turning?

A: No, UC5115 is specialized for Cast Iron. For steel, we recommend UE6110 or MC6025 grades for better results.

Q: What is the benefit of the GH chipbreaker?

A: The GH geometry provides a stronger edge designed specifically for heavy-duty roughing and interrupted cuts where stability is paramount.

Q: How many cutting edges does this insert have?

A: WNMG is a double-sided trigon shape, giving you 6 usable cutting edges, which is more economical than CNMG.

Expert Machining Tip: UC5115 vs MC5015

For General High-Speed Cast Iron work, UC5115 is excellent. If your application involves Highly Abrasive Ductile Iron, consider the MC5015 grade for even higher wear resistance.

Technical FAQ & Buying Guide

Are your carbide inserts interchangeable with major brands like Sandvik, Iscar, or Kennametal?

Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.

How do I choose the correct insert grade and chipbreaker for machining Stainless Steel (M) vs. Carbon Steel (P)?

We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:

  • For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
  • For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
What are the recommended cutting speed (Vc) and feed rate (f) parameters to maximize tool life?

The optimal cutting parameters vary depending on the workpiece hardness and operation type:

  • For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
  • For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
Do you offer bulk discounts or wholesale pricing for machine shops and distributors?

Yes, we support machine shops, distributors, and global buyers with tiered wholesale pricing and competitive volume discounts. We also provide OEM custom manufacturing solutions for tool holders and carbide inserts based on your technical drawings. Contact our team to request a quick B2B quotation.

What is your international shipping policy and typical lead time for orders?

We provide secure worldwide express shipping (via DHL, FedEx, and UPS) with specialized, vibration-proof industrial packaging to ensure tools arrive in perfect condition. In-stock items are dispatched within 24-48 hours, while custom or bulk orders typically have a stable lead time of 15-25 days.

How do you guarantee the quality and tolerance precision of your CNC tools?
